Abstract: The edge-cloud collaboration platform for intelligent coking monitoring of cracking furnace tubes includes an edge layer and a cloud layer, which can store and analyze big data, propose suggestions on optimization and improvement, and feed the suggestions back to the edge layer. The edge layer includes an intelligent temperature measuring device for an outer surface of a cracking furnace tube and/or an ethylene DCS/data acquisition device; the cloud layer includes a cracking furnace safety warning device, an intelligent coking diagnosis and prediction device for a cracking furnace tube, a hybrid job scheduling device, a multi-workflow scheduling device, a virtualized resource scheduling device, and a virtual resource optimization device; and the intelligent temperature measuring device for an outer surface of a cracking furnace tube includes an identification device for furnace tube and overlapped tube, and an abnormal data detection device.

Abstract: The present invention discloses a large-scale semi-rigid structure airship, relating to the technical field of aerostats, which comprises a ship body, vector side thrusters, a vector tail thruster, an X-shaped inflatable tail fin, air cushions, and a pod, wherein the ship body comprises a pretensioned capsule and a tensegrity keel; the pretensioned capsule is sleeved onto an outer surface of the tensegrity keel in a pretensioning mode; the vector side thrusters are provided at lower-side portions of the ship body; the vector tail thruster is provided at the tail of the ship body; the X-shaped inflatable tail fin is arranged at the tail of the ship body in an X shape; the air cushions are provided at lower portions of the ship body; and the pod is provided at a lower portion of the ship body.
